GAS-BURNER.

Specification of Letters Patent.

Applicationfiled August 16, 1918. Serial No.. 250,148.

To all whom it mag concern Be it known that we, CARL OLSEN and PETER PIMLOTT, citizens of the United States, residin at Brooklyn, in the county of Kings and gtate of New York, have invented certain new and useful Improvements in Gas-Burners, of which the following is a specification.

This invention relates to improvements in liquid and gaseous fuel burners, and it is the principal object of the invention to provide afue1 burner of the superheating type whereby the. fuel supplied thereto is reduced to a highly combustible gas during its passage over the burner flame and is then sup-- plied to the burner for combustion.

Another and equally important object of the invention is to provide the burner with a form of gas pressure equalizing means into which the gas generated by the burner is discharged and permitted to pass to the burner proper in such a manner as to produce an even and uniform flame. It is also an object of the invention to provide the retort portion of the burner with means for preventing the back flow of gas therefrom, hence, insuring the production of an efiectual flame at the burner.

The improvements in the details and arrangement of parts will be apparent from an inspection of-the accompanying drawings, in connection with the specific description hereinafter contained, and wherein the preferred embodiment of the invention is disclosed for the purpose of imparting a full understanding thereof.

In the drawings:

Figure 1 is a top plan of the burner,

Fig. 2 is a longitudinal section therethrough, and

Fig. 3 is a transverse section through the same.

Referring more specifically to the drawings, in connection with which like reference characters will designate corresponding parts throughout the several views, 1 represents the retort of the burner, the same consisting of a pipe coil, one extremity of which is raisedabove the main portion of the coil as indicated at 2 and is tapped into the upper end of a pressure equalizing conduit inchamber 3, the lower end of this chamber having one end of a burner pipe 4 tapped thereinto, which pipe, as will be noted, is formed with a plurality of longitudinally arranged burner openings 5. In this connection, it is to be noted that the burner pipe 4 is arranged directly under the retort chamber formed by the pipe coil 1 and that the upper extremity 2 of the pipe coil is provided with a suitable form of adjustable flame deflector ,6, for an obvious purpose.

Engaged with the remaining or free end of the retort chamber or pipe coil is a check valve 7 having a suitable form of nozzle 8 connected thereto whereby to reduce the flow of fuel into the retort chamberin order that the same can be reduced to gas in the least possible time to a combustible gas. It of course will be understood that the check valve 7 has connection with'a suitable form of supply pipe 9 extending from a reservoir or other source of supply, not shown, further, that if desired, suitable cut-ofl means, not shown, can be interposed in the supply pipe 9 whereby to regulate flow of fuel to the burner.

For starting the burner, a fuel pan 10 is provided and is arranged under theburner pipe 4 and secured theretoby passing metal straps 1 1 over the same and engaging their opposite ends with portions of the pan. Into this pan, a suitable form of combustible liquid is placed and when ignited will heat the liquid fuel passing through the. retort chamber to an extent to cause its reduction to combustible gas for ignition at the burner openings of the burner pipe 1; Due to the manner in which the liquid fuel is discharged into the retort chamber or pipe coil 1, it will be understood that reduction of the same to gas by heating of the pipe coil can be accomplished in the least possible time.

The gas generated in the retort chamber of pipe coil upon operation of the burner is discharged therefrom into the equalizing chamber 3, which as hereinbefore stated,'is of a diameter greater than-the diameter of the pipes forming the retort. As a consequence, the gas discharged from the equalizing chamber into-the burner pipe twill be under an even-and uniform pressure and in consequence, an even and uniformlflame will be producedthereby. Back pressure of the gas when generated will be prevented due to the positioning of'the check valve 7 therein, insuring proper functioning of the burner.

Manifestly, the construction shown" is capable of considerable modification and such modification as is within the scope of our claims, we consider within the spirit of our invention.

We claim:

The combination with a fuel pan, of a gas burner comprising a hollow body forming a pressure equalizing chamber resting within the pan at one end thereof, a burner pipe tapped into the hollow body near the lower end thereof and extending normal thereto, and a retort including a coil pipe having spaced parallel stretchers, one of said stretehers being tapped into the upper portion of the hollow body, and the other stretchers extended on opposite sides of said body and about the same, the first named stretcher of the coil being disposed superposed relative to the burner pipe and directly over the same in parallel relation thereto.

In testimony whereof we afiix our'signa- 20 tures hereto.

CARL OLSEN. PETER PIMLOTT.
